SwiftPatch vs Expo Updates: A Deep Dive

Introduction

If you're building a React Native app, you've likely considered two major OTA update solutions: Expo Updates (EAS) and SwiftPatch. Both let you push JavaScript updates without App Store review, but they take very different approaches.

This guide breaks down the key differences to help you choose the right platform for your team.

Quick Comparison

Feature	SwiftPatch	Expo Updates (EAS)
Works with bare RN	Full support	Limited
Patch Size	98% smaller (differential)	Full bundle
Auto Rollback	Yes (< 3 seconds)	No
Free Tier	5,000 deploys/mo	1,000 updates/mo
Self-Hosting	Available	No
Expo Ecosystem	Compatible	Native
Pricing	$79/mo (Team)	$99/mo (Production)

When to Choose SwiftPatch

1. You Have a Bare React Native Project

SwiftPatch was built for bare React Native projects from day one. If you're not using Expo's managed workflow, SwiftPatch integrates seamlessly without any additional configuration.

2. You Need Smaller Patches

SwiftPatch uses differential patching, sending only the bytes that changed between versions. This means:

• 98% smaller updates (20MB → 200KB average)
• Faster downloads for users
• Lower bandwidth costs
• Better performance on slow networks

Expo Updates sends the entire bundle on every update, which can be problematic for larger apps.

3. You Want Automatic Rollback

SwiftPatch monitors your app after each update. If a crash is detected, it automatically rolls back to the previous stable version in under 3 seconds. Expo Updates requires manual intervention.

4. You Need Self-Hosting

For enterprises with strict data residency requirements, SwiftPatch offers a self-hosted option. Deploy on your own infrastructure with full control over your update pipeline.

When to Choose Expo Updates

1. You're Deep in the Expo Ecosystem

If you're using Expo's managed workflow and EAS Build, Expo Updates is the natural choice. It integrates seamlessly with the rest of the Expo toolchain.

2. You Want Simplicity

Expo Updates is straightforward to set up if you're already using Expo. The configuration is minimal and it "just works" within the Expo ecosystem.

3. You Use Expo's Build Service

If you're using EAS Build, Expo Updates pairs naturally with it. All your tooling stays within the Expo platform.

Detailed Feature Comparison

Patch Size & Delivery

• Binary-level differential patching
• Only changed bytes are transmitted
• Average patch: 200KB (vs 20MB full bundle)
• CDN-delivered globally

• Full bundle on every update
• Entire JavaScript bundle re-downloaded
• Can be slow on large apps
• Uses Expo's CDN infrastructure

Rollback Capabilities

SwiftPatch:

1. Update deployed
2. User downloads update
3. App monitors health for 30 seconds
4. If crash detected → automatic rollback
5. Rollback completes in < 3 seconds

Expo Updates:

1. Update deployed
2. User downloads update
3. If crash occurs → app continues crashing
4. Developer must push a fix manually
5. Users affected until fix is downloaded

Pricing Comparison

• Free: 5,000 deploys/mo, 2 apps
• Indie ($19/mo): 25,000 deploys/mo, 5 apps
• Team ($79/mo): 100,000 deploys/mo, unlimited apps
• Enterprise (Custom): Unlimited + self-hosting

• Free: 1,000 updates/mo
• Production ($99/mo): 25,000 updates/mo
• Enterprise (Custom): More updates + priority support

For most teams, SwiftPatch offers better value with more deploys at a lower price point.

Developer Experience

SwiftPatch CLI:

# Deploy an update
swiftpatch release --platform ios

# Staged rollout
swiftpatch release --platform ios --rollout 10

# Check deployment status
swiftpatch status

Expo Updates CLI:

# Deploy an update
eas update --branch production

# Check status
eas update:list

Both provide solid CLI experiences, though SwiftPatch offers more granular control over rollouts.

Migration from Expo Updates to SwiftPatch

If you decide SwiftPatch is right for you:

# Install SwiftPatch
npm install swiftpatch

# Run migration (auto-detects Expo config)
npx swiftpatch migrate --from expo

# Deploy first update
swiftpatch release --platform ios

Conclusion

Both SwiftPatch and Expo Updates are solid choices, but they serve different needs:

• You have a bare React Native project
• Patch size matters to you
• You need automatic rollback
• You want a lower price point
• Self-hosting is a requirement

• You're fully in the Expo ecosystem
• Simplicity is your priority
• You use EAS Build extensively
